Systems and methods for hemorrhage control and or tissue repair

1. A method for controlling bleeding and promoting hemostasis within a hollow body organ of a gastrointestinal tract selected from one of an esophagus, a stomach, a duodenum, a small intestine, and a large intestine comprising:

identifying within the hollow body organ, a tissue treatment region requiring bleeding control with a layered bandage application system comprising a tubular bandage structure, a hollow substantially cylindrical expandable body, and a sleeve;

providing the tubular bandage structure having a normal interior diameter, the tubular bandage structure comprising a chitosan material, the tubular bandage structure being sized and configured to radially enlarge beyond the normal interior diameter in response to application of radial expansion force;

providing the hollow substantially cylindrical expandable body sized and configured to expand between a collapsed condition having a first diameter approximating the normal interior diameter and an expanded condition having a second diameter greater than the first diameter;

providing the sleeve;

providing the bandage application system in conjunction with a detachable endoscopic device;

sliding the sleeve over the endoscopic device so as to allow viewing capability from the endoscopic device tip;

sliding the hollow substantially cylindrical expandable body over the sleeve in the collapsed condition;

forming the bandage application system by mounting the tubular bandage structure on the hollow substantially cylindrical expandable body;

introducing the bandage application system and the endoscopic device into the hollow body organ;

applying radial expansion force to the tubular bandage structure by expanding the hollow substantially cylindrical expandable body from the collapsed condition to the expanded condition to radially enlarge and press the tubular bandage structure within the hollow body organ against all sides of the entire inner circumference of one of the esophagus, the stomach, the duodenum, the small intestine, and the large intestine that includes the tissue treatment region;

maintaining the hollow substantially cylindrical expandable body in the expanded condition for a period of time sufficient to exert pressure on the radially enlarged tubular bandage structure to adhere the radially enlarged tubular bandage structure to all sides of the entire inner circumference of one of the esophagus, the stomach, the duodenum, the small intestine, and the large intestine that includes the tissue treatment region, whereby bleeding of the tissue will be controlled by sealing the tissue treatment region and creating an active clotting surface;

releasing the radial expansion force by collapsing the hollow substantially cylindrical expandable body from the expanded condition to the collapsed condition; and

removing the hollow substantially cylindrical expandable body from the hollow body organ without displacing the adhered and radially enlarged tubular bandage structure;

wherein the radially enlarged tubular bandage structure defines a center hole through which food can pass through the gastrointestinal tract.

2. The method according to claim 1 , wherein the bandage application system is introduced under video guidance.

3. The method according to claim 1 , wherein the bandage application system is introduced under fluoroscopic control.

4. The method according to claim 1 , wherein the hollow substantially cylindrical expandable body is expanded using a gas or fluid.

5. The method according to claim 1 , further including providing a protective barrier on the bandage application system so that the tubular bandage structure does not adhere to the bandage application system or to tissue en route to the tissue treatment region.

6. The method according to claim 1 , further including providing an outer sheath on the bandage application system to protect the tubular bandage structure from wetness within the hollow body organ.

7. The method according to claim 1 , wherein the tubular bandage structure is processed through the digestive system.

8. The method according to claim 1 , wherein the hollow substantially cylindrical expandable body is maintained in the expanded condition for about two to five minutes.

9. The method of according to claim 1 , further including repeating the method and applying an additional bandage.

10. The method of according to claim 1 , wherein the sleeve consists of a polymeric material.

11. The method of according to claim 1 , wherein the hollow substantially cylindrical expandable body is an expandable sleeve.

12. The method of according to claim 1 , further including at least one locking ring fitted over an end of the sleeve.

13. The method of according to claim 1 , further including the step of pushing the bandage application system off of the endoscopic device before applying radial expansion force to the tubular bandage structure.

14. A method for controlling bleeding within a hollow body organ of a gastrointestinal tract selected from one of an esophagus, a stomach, a duodenum, a small intestine, and a large intestine comprising:

identifying within the hollow body organ, a tissue treatment region requiring bleeding control with a bandage application system comprising a sleeve suitable for sliding over an endoscopic device, a hollow expandable body surrounding the sleeve, and a tubular bandage structure surrounding the hollow expandable body;

providing the endoscopic device;

preparing the bandage application system by sliding the sleeve over the endoscopic device;

mounting the hollow expandable body onto the sleeve;

mounting the tubular bandage structure onto the hollow expandable body;

introducing the bandage application system into the hollow body organ;

pushing the bandage application system off of the endoscopic device before adhering the tubular bandage structure to the tissue treatment region;

adhering the tubular bandage structure to the tissue treatment region by expanding the hollow expandable body to radially enlarge and press the tubular bandage structure against all sides of the entire inner circumference of one of the esophagus, the stomach, the duodenum, the small intestine, and the large intestine that includes the tissue treatment region;

sealing the tissue treatment region by adhering the tubular bandage structure, whereby bleeding of the tissue will be controlled;

collapsing the hollow expandable body from the expanded condition to a collapsed condition; and

removing the bandage application system from the hollow body organ without displacing the tubular bandage structure;

wherein the radially enlarged tubular bandage structure defines a center hole through which food can pass through the gastrointestinal tract.

15. The method according to claim 14 , further including maintaining the hollow expandable body in the expanded condition for a period of time sufficient to adhere the radially enlarged tubular bandage structure.

16. The method according to claim 15 , wherein the hollow expandable body is maintained in the expanded condition for about two to five minutes.

17. The method according to claim 14 , wherein the bandage application system is introduced under video guidance.

18. The method according to claim 14 , wherein the bandage application system is introduced under fluoroscopic control.

19. The method according to claim 14 , wherein the hollow expandable body is expanded using a gas or fluid.

20. The method according to claim 14 , wherein the hollow expandable body is substantially cylindrical.

21. The method according to claim 14 , further including providing a protective barrier on the bandage application system so that the tubular bandage structure does not adhere to the bandage application system or to tissue en route to the tissue treatment region.

22. The method according to claim 14 , further including providing an outer sheath on the bandage application system to protect the tubular bandage structure from moisture.

23. The method according to claim 14 , wherein the tubular bandage structure is processed through the digestive system.

24. The method of according to claim 14 , further including repeating the method and applying an additional bandage.
